Y IMPROVEMENT iN HARVESTERS.

Specification forming part of Letters Patent No. 105,399, dated July 12, 1870. n

VTo all whom't may concern:`

Be it known that we, CALEB W. WITT and BENNETT FfWITT, of Indianapolis, in the county of Marion and- State of Indiana, have invented certain Improvements in Reapers, of "which the following isa specification, reference being had to the accompanying drawings.`

Our invention relates to reapers; and it consists of a novel constructionand arrangement of devices for conveying the cut grain from the platformto a receptacle where it is to be bound, as'hereinafter explained.

Figure l is atop plan view. Fig. 2' is a transverse sectionon the, line w tof Fig. 2,- :looking from the front; and Fig. 3 is aview ofa portion shown detached.

We make the main frameA or body A of our `machine with a tight` box to receive the shelled grain, and in which box the binder rides. This body is mounted von two wheels, as shown in' Fig. 1, and has projecting from .i one side a platform, B, to be provided with the usual cutting apparatus. (Not shown inl v At each side of the platform'is located a shaft, t, as shown in Fig. 2, and on these shafts is'mo'unted `a series of sprocket- Wheels, around which are stretched a series of endless'chains, C, which inclose the platform B, as represented. At the inner sideof the' platform is arranged, in an inclined position, a series of strips, G, which extend from the platform up to. the top of the box A, there being aspace leftbetweenjeach of the adjoining strips. In front; of these'strips G,

` and just over the platform, is mounted a shaft,

p, having a seriesof pulleys thereon, and a little distance above the top of the strips G is mounted anothershaft, N,a1so having a lcorresponding series' of wheels, R, and around these two shafts we place a series of endless chains, D, parallel with the strips G, as shown in Fig. 2. This chainv D is composed of a series of solid bars, @,connected byopen links d, pivoted thereto `at each end, asl shown in Fig. 3, and ataintervals the solid partso are provided with projectingnspurs'e, which are c slightly inclined, as represented in Figs. 2 and `:,`these`spurs being of suflcient length to reach to the spaces between i; the` strips G, in which spaces their outer eudspass as the chains move.

The wheels R uponthe shaft N are made with a series of double -inclined projecting points, m, which lit into the open links d, andwith notches l, into which the joints of the links fit, as shown in Fig. 3. vThe chains C on the platform are made in the same manner, except. that the projections or lingers a are ofless length, and differ somewhat in form'.

Upon the frame, directly over the upper ends of the strips G, we `secure a corresponding series of strips or guards, H, the lowerv ends of which are curved outward, so as to Vproject in between the chains D, as represented in Fig. 2. On the inside of the box A we locate a trough or receptacle, J, to receive the grain'asit is carried up by the chains D, and `falls over into the box, where it is bound by hand.

It will be observed that the inclination -of the projections or lingers e, and the curvature and inclination of the guardsH, are such that, while the grain is sure to be carried under the outer ends of the guards, it slips easily off from .the lingers e, and falls at once into th trough J.

Motion is conveyed to thechainsD by means of a similar chain, P, (without the ngers,) which passes around a wheel like 'R on the hub of the outer bearing-wheel, and thence up around a similar wheel, T, on the end of a shaft, I, which extends across the rear end of the main frame, and has on its opposite end a bevel-gear, U, which engages with a similar gear-wheel,V,on a counter-shaft carrying a pinion, F, which latter engages' with a corresponding pinion on the shaft N, as shown in Fig. 1. On this counter-shaft r is mounted another sprocket-wheel, aroundwhich passes a chain, f, which also passes around the shaft t at the inner side of the platform, and thereby imparts motion to the chains G.

The grain, as it is cut, falls on the chains C, and is carried along by them toward the box A until it passes under the chains D, the fingers e of which, as they pass around, force it up the inclined strips G, and under-the guards H, over the side of the box into the trough J,

Where it is bound, the grain that is accidentally shelled by the handling of it being preserved in the box A. v

The machine may be made so as to be used with one horse, or with more, as preferred.

By this method of constructing the parts we are enabled to produce a very simple, efy cient, and durable machine.

Having thus described our in=vention,what

We claim is- 1. The arrangement of the chains C, the inclined strips Gr, chains D, and the clearers'H, in a harvester, substantially as described.

2. The chains D, provided with fingers e, arranged to pass between the chains C, and also between the strips G, as shown, for the purpose of insuringthe lifting of the grain from the platform, as set forth. I
